Blind Advocates Tell Hybrids to Make Some Noise

Hybrid cars are gaining popularity around the U.S. because they are eco-friendly, but their silent engines are generating criticism from advocates of the blind.

Those who have lost their sight said the cars can be dangerous because they have come to rely on hearing oncoming traffic.

The National Federation of the Blind is lobbying automakers to add noisemakers to their hybrid cars.

Guide Dogs for the Blind has begun incorporating hybrids into its training, teaching students and their dogs to be aware that hybrids can sneak up on them.

Officials with the organization said driver awareness could be the most effective solution to the problem.

"Just be very vigilant when you are turning at intersections for pedestrian safety, especially if you are in a hybrid," said Ken Altenburger, who is blind.

California has the highest concentration of hybrids in the nation.

None of the major automakers have responded to the lobbying with any changes to their hybrids.
